Abstract (en)
A layered film structure comprising a core layer C and external layers E1 and E2, wherein core layer C comprises a multimodal ethylene terpolymer (I) with at least one C<sub>4</sub> to C<sub>12</sub> alpha-olefin having an MFR<sub>5</sub> determined according to ISO 1133 of from 0.1 to 5 g/10 min and a density of 0.934 to 0.940 g/cm<sup>3</sup> and a recycled LDPE having a MFR<sub>2</sub> determined according to ISO 1133 of from 0.1 to 10 g/10 min and a density in the range from 910 to 940 kg/m<sup>3</sup> and wherein external layer(s) E1 and/or E2 comprise(s) a multimodal ethylene terpolymer (II) having an MFR<sub>2</sub> determined according to ISO 1133 of from 0.5 to 10 g/10 min and a density of 0.920 to 0.935 g/cm<sup>3</sup>.
